Kourtney Kardashian feels Scott Disick should treat her with more ''respect''.

The 39-year-old reality star - who has kids Mason, eight, Penelope, six, and Reign, three, with her ex-boyfriend - slams Scott in a clip from an upcoming episode of 'Keeping Up With The Kardashians', arguing he ought to be more appreciative of his relationship with her family.

After Kourtney accuses Scott of doing ''whatever'' he wants, he responds: ''What's whatever I want? Live my life the exact same way you're living it?''

Kourtney replies: ''It's called giving someone a heads up and having a respectful conversation, giving someone the respect.''

The brunette beauty also refuses to accept Scott's explanation that, at times, some things don't go as expected.

She added: ''Yeah, but that could also just be an excuse. I make sacrifices all the time and you're not following through with the things you say you're going to do. And then you just go do whatever you want and I'm not okay with it.''

However, Scott subsequently claims that Kourtney often has unrealistic expectations of other people.

He said: ''I think you expect a lot from a lot of people, but not always can your expectations be met, even though people are trying their hardest to please you.''

Meanwhile, a source recently claimed that Kourtney ''distanced herself from her sisters'' during romance with Younes Bendjima.

The reality star split from the model in early August after almost two years of dating, and it's been suggested that their split could improve Kourtney's relationship with her sisters.

The insider explained: ''Kourtney was always so private and closed off when it came to Younes, and that really distanced herself from her sisters. Things are fine with them now and I'm sure they'll get even more back to normal now that it seems he's out of the picture for good.

''This could be a really positive thing for her relationship with her family.''
